Salman Abedi, 23, has been identified as the Manchester Arena suicide bomber

Manchester Police tweeted on Tuesday morning that a 23 year old man has been arrested in connection with the attack at Manchester Arena in the UK on Monday.

Two explosives were detonated as concert-goers at an Ariana Grande 'Dangerous Woman Tour' stop were exiting the venue.

22 people, including children, were killed and 59 people were injured.

12 children under the age of 16 were among the 59 injured, the Associated Press reports a UK ambulance official said

Shortly after the Manchester Police tweet, the AP reported that the Islamic State has taken responsibility for the terror attack.

Authorities previously announced that they believed the attack to be the work of a suicide bomber and that they had identified that person, however, because of the sophisticated nature of the attack, the question of whether or not additional people were involved existed.
